NOVELTY – The nano-crystalline titanium dioxide solar cell comprises a system sensitized by a dry polymer electrolyte, without presence of solvent. The electrolyte is the elastomer (Epichlomer-16): poly epichlorohydrin-co-oxide of ethylene, charged with NaI and I2. EMBODIMENT – The salt promotes ionic conduction, and the redox pair facilitates operation of a photo-electrochemical cell. USE – In power engineering.

Main Application Field

A85 (Electrical applications.); L03 (Electro-(in)organic – chemical features of conductors, resistors, magnets, capacitors and switches, electric discharge lamps, semiconductor and other materials, batteries, accumulators and thermoelectric devices, including fuel cells, magnetic recording media, radiation emission devices, liquid crystals and basic electric elements. Growing of single crystals of semiconductors and their doping are included, but semiconductor devices, where the manufacture is not claimed are excluded. Electrography, electrophotography, magnetography, electrolysis, electrophoresis, power plant, X-ray and plasma-techniques, ion exchange resins, polyelectrolytes, electroplating, metal electrodeposition, electroforming, anodising, electrolytic cleaning, cathodic protection and electrolytic or electrothermic production or refining of metals are all covered elsewhere (Sections G, J, K and M).); U12 (Discrete Devices); X15 (Non-Fossil Fuel Power Generating Systems)
